I used to have this book of studies years ago & mislaid it, but had such good memories of it that I bought it again. Mostly I play them on saxophone, which is great as then there are lots of altissimo register notes to make me work hard! The studies vary in style & difficulty, though all are reasonably challenging. There is one really good one with lots of octave leaps in a 3/3/2 time signature. Highly recommended.
